The Los Alamos free-electron laser (FEL) facility has been greatly modified by the replacement of the thermionic electron gun and bunchers with a 1300 MHz RF photoinjector. Two more accelerator tanks have been added to increase the beam energy to 40 MeV. Preliminary studies at 15 MeV have demonstrated excellent beam quality with a normalized emittance of 40 {pi} mm-mrad. The beam quality is now sufficient to allow harmonic lasing in the visible. At present we are beginning FEL experiments at a wavelength near 3 {mu}m. In this paper we report on the performance of our photoinjector accelerator. 9 refs. , 3 figs., 4 tabs.
